A20-Lime2 Poky build Kernel panic

[gaminn]

I was able to build core-image-base image for A20-Lime2 using poky and meta-sunxi layer (no custom configuration made). I mounted generated image (sunxi_sdimg file) on a SD card.

During A20-Lime2 booting I get Kernel panic.

Can you help?

See where it is looking for init and then check if it's there (clearly it isn't) - and either change where it looks or put init there.

Problem is solved. It happened that although dd command that copies image to the sd card finished, the image (namely linux partition) actually wasn't copied well. Today, it works...
